Radioactive Aerosols under Conditions of New Safe Confinement in 2018

Nuclear Power and the Environment, 2020
The results of monitoring of radioactive aerosols emissions from the Shelter object in 2018 are given. The maximum value of «unorganized» release rate was observed in November and was 4.6 kBq/(m2 ∙ day). The completion of construction and sealing of the enclosing contours of the New safe confinement (NSC) in 2018 completely limited the influence of ...

CFD MODEL AS A DIGITAL TWIN OF THE RADIATION STATE OF THE NEW SAFE CONFINEMENT OF THE CHERNOBYL NPP

Problems of Atomic Science and Technology, 2020
The necessity of a detailed analysis and prediction of the operating parameters and distribution of radioactive aerosols (RA) in the Shelter Object (SO), the New Safe Confinement (NSC) and the environment of the Chernobyl NPP over the 100-year life of the NSC during the extraction of radioactive waste (RW) from the SO is being justified.

Features of Neutron Flux Density and Gamma-Radiation Exposure Dose Rate Dynamics in ChNPP Shelter Object after the New Safe Confinement Commissioning

Nuclear Power and the Environment, 2023
The nuclear safety monitoring system (NSMS), which is a part of the integrated automated monitoring system (IAMS), was created within the framework of measures aimed to build the New Safe Confinement — Shelter Object complex (hereinafter NSC-SO) before the protective arch itself was slide into design position. During NSMS operation period, the attempts

On Geological and Geophysical Safety of the New Safe Confinement for ChNPP-4

Nuclear and Radiation Safety, 2016
The paper considers evidences and mechanisms of potential impact of local depression (microgeodynamic) zones on NPP safety. The depression forms were revealed within the Chornobyl NPP site, including location of the new safe confinement. Nature of zones and character of their influence is determined by fault structures and conjugated deep degassing ...

Measuring the equivalent dose rate over the Shelter object after completion of the New Safe Confinement

Nuclear Power and the Environment, 2020
An experiment on measuring the equivalent dose rate over the Shelter object after the completion of the construction of the New Safe Confinement is described. Measurements of the gamma radiation were performed in the time of commissioning of the New Safe Confinement with the help of the sensor installed on its Main Cranes System.
